基于ZigBee技术无线教学系统的设计与实现

ZigBee是一种短距离、低功耗的新兴无线网络技术。为改善教学模式、降低教学成本，采用CC2430芯片构成无线网络节点，设计了一种基于ZigBee技术的无线网络教学系统，阐述了ZigBee技术在无线教学网络中的应用、通讯协议以及无线ZigBee节点的软硬件设计。系统中教师使用协调器，学生使用路由或终端节点，通过一台掌上学习机可以实现师生通信和在教师控制下的学生之间的通信。系统安装方便、智能高、可扩展性强，符合现代教学系统的发展趋势。

Wireless Network Teaching System Based on ZigBee

This paper introduces a wireless teaching system based on Zigbee technology.The wireless network node is conmposed of CC2430.It describes the ZigBee wireless network application,communications protocol,hardware and software design of the ZigBee nodes.In this system,teachers can use the coordination,while students use the router or terminal nodes so teacher-student communication and student-student communication under the control of the teacher are realized by using a PDA.
